Street Views of the Water

The way maps are produced and displayed varies greatly, depending on their extent, their intended use, and the peculiar challenges of each environment. Mapping a...

After the Storm

Lately, large storms such as hurricanes, cyclones, and typhoons have been wreaking havoc...

The Data of River Dynamics

Using GIS tools and readily accessible satellite data to study rapid change in rivers. Editor’s note: The dynamics of rivers can range from relatively stable to rapidly shifting, the latter especially in flood-prone regions exacerbated by a global increase in extreme weather events. The impacts are environmental, but also economic, social, and cadastral. Surveyors, for...

Surveying Beyond the Water’s Edge

A remotely controlled unmanned survey vessel gives a land survey crew full hydrographic abilities for two busy marinas in Oregon. Founded in 2005, Statewide Land Surveying (SWLS) is a small business located in Gresham, Oregon, well acquainted with taking on challenging projects. While mostly engaged in land surveying, SWLS crew members have been involved for over...

Surveying Scientists: The USGS Does It Right

As is often the case in our tightly networked profession, one thing leads to another. In early 2017 I was contacted by the US Geological Survey (USGS) hydrologist, Brenda Densmore, from the USGS Nebraska Water Science Center. Brenda had found me through the NGS State Geodetic Coordinator web page and reached out to me for...

Michelle Japitana

Instructor and Concurrent Chairman, Engineering Sciences Department, Carga State University, Philippines Testimonials for Michelle Japitana were remarkable. (This year we received a record number of nominations from the Philippines, and we wish we could honor all the fine candidates.) Michelle’s nominators noted that her strength in the geospatial community is her research capabilities in the fields...
